An elevator is moving downward when someone presses the emergency stop button. the elevator comes to rest a short time later. give the signs for the velocity and the acceleration of the elevator after the button has been pressed but before the elevator has stopped. enter the correct sign for the elevator's velocity and the correct sign for the elevator's acceleration, separated by a comma. for example, if you think that the velocity is positive and the acceleration is negative, then you would enter ,- . if you think that both are zero, then you would enter 0,0 .

Suppose that f : rn → rm and that a ∈ k, where k is a connected subset of rn . suppose further that for each x ∈ k there exists a δx > 0 such that f(x) = f(y) for all y ∈ bδx (x). prove that f is constant on k; that is, f(x) = f(a) for all x ∈ k
